碩士 === 國立高雄第一科技大學 === 系統資訊與控制研究所 === 100 === In our study based on Interval Type-2 Fuzzy Logic Controller. Consider the Stewart Platform is high complexity system of uncertainty and imprecision information to design and testing. Extension of Fuzzy Logic Interval improved design to find out the best characteristics of response. A new approach Two Hierarchy Switching Interval Fuzzy Logic Systems based on six interval Footprint of Uncertainty (FOU) range be proposed. The high level linguistic control rules consist of expert knowledge and experiences. In the same situation case, the performance of IT2FLC compare effectively with T1FLC through the command voltage signals and the experimental results such as the step and sinusoidal tracking responses. Hence, the proposed controller is feasibility and effectiveness.
